The Muncie A20-A1006-HX3BBXX or A20A1006HX3BBXX is a medium-duty, clutch shift power take-off from Muncie's A20 Series, designed specifically for Allison 3000 and 4000 Series transmissions via a 10-bolt mount. The shift cover allows 360-degree rotation, and the rotatable pump flange simplifies pump positioning during installation. Tapered roller bearings extend service life, while an increased-diameter output shaft improves durability under sustained load. The housing incorporates reduced leak paths and a gear profile optimized for noise reduction. Three housing arrangements are available, and the unit is compatible with the EX Drive shaft extension.
